To all whom it may concern:

Be-it known that I, QEN Manners, a citi zen of the United States, residing at Boise, in the county of Ada and State of Idaho, have invented a new and useful Ore-Separator, of which the following is a specification.

This invention relates more particularl to means for separating old from the so' in which it is located, an the principal object is to provide a simple structure of a novel nature that will effectively separate and conserve the gold, will successfully operate with a very small quantity of water, and is not liable to become choked or clogged with the material from which the desired metal is secured.

The preferred form of construction is illustrated in the accompanying drawings,

wherein:-

Figure 1 is a side elevation of the machine. Fig. 2 is a vertical longitudinal sectional view therethrough. Fi 3 is a cross sectional view. 4 is a detail horizontal sectional view, showing the gearing for operating the concentrator belt. Fig. 5 is a detail perspective view of one of the aprons. Fig. 6 is a detail erspective view of a portion of the water de ivering means. Fig. 7 is a detail perspective view of one of the supports for the belt carrying frame. Fig. 8 is a detail sectional view on the line 88 of Fi 1. Fig. 9' is a face view of the driving whee for the pump.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the structure disclosed, a su porting frame is employed, comprising standhrds 10, upper and lower longitudinal beams 11, and cross beams 12. Mounted on one end of the frame are grooved rollers 13, while other smooth faced rollers 14 are journaled on a bracket 15 that is located on an intermediate portion of the frame, and is vertically ad- Lpstable thereon. This bracket, as shown in ig. 3, has depending le 16, provided with upright slots 17, throug which arepassed hold screws .18 that are threaded into the upper eams 11. A rota screen or grizzly 19 is supported on the ro ers, and while for ordinary urposes, the screen may have, a single wa where the material to be separated is heavy and includes large rocks and the like, a double screen is preferably employed. Thus in the present embodiment, an inner coarse screen 20 is surrounded by a finer screen 21, the inner screen inclosing a feeding coil 22 comprising a heavy rod or wire. The screen at one end has a hoop 23 provided with an annular outstanding flange- 24 that engages in the grooves of the rollers 13. Another hoop 25 at the lower end of the screen rests upon the smooth faced rollers 14. The screen walls 20 and 21 at the lower end are held in spaced relation by s aced webs 26, which permit the outflow 0 material that is fine enough to pass through the coarser screen 20 -or too coarse to pass through the finer screen 21. A rearwardly extending arm 27, secured 'to the bracket 15, constitutes a su port for a swinging tailings discharge trougii the lower end of the rotary screen, and has a depending pintle 29 at its u per end that is journaled in the rear end of t e arm 27. B this means, it will be evident that the troug may be placed, so as to deliver from either side of the machine, as desired. The mate rial is fed to the screen by an inclined chute 30 that is located at its upper end, and is supported by suitable brackets 31.

Oppositely inclined aprons are located beneath the screens. As these aprons are substantially duplicates, a description of one is believed to be sufficient for both. Each apron consists of an oblong frame 32, set at an inclination, and having the aplron body detachably mounted thereon. his body includes a longitudinally disposed central bar 33 and sets of cross clamping bars 34, the said bars for bars constituti the end walls of said pockets. Horizonta y disposed bottoms 35am provided for these pockets, said bottoms eing formed of sheets that extend on sub stantially the length of the bodies and are located and clamped between the cross bars of the different sets, as clearly shown in Fig. 2. It will be observed that the bottoms are horizontally disposed and each is located in a plane lower than the one in advance of it. The pockets, thus produced, are very shallow, and the intermediate portions of the lower end walls project above the bottoms not over one-eighth of an inch. At the corners, however the end walls extend higher, beingprovided with substantially triangular projections 36. The purpose of 28 that is located in rear of pockets, the cross o ening 38 disposed over a downwardly ined guide pan 39, fastened at its u per end, as showniat 40 to one of thecross ars of the frame, its lower end'being sus ended the frame. a e

The aprons are relatively adjustable, and for this purpose, links 42 are provided, the said links being secured to the upper end of the upper apron and to the lower end of the lower apron. These links .have openings 43 therethrough, through which are passed fasteners 44 that engage said lower apron.'

Thus the distance between the upper end of the upper apron and the lower end of the lower apron can be varied, so that their relative angle may be changed. The aprons are furthermore supported on upright leaf springs 45, the'lower ends of these springs being located inside the lower side bars 11 of the frame, and being'adjustably secured thereto by clamp plates 46. that extend across the springs. and frictionally engage the same, being held in such frictional engagement by fasteners 47 passed through the clam ing plates and into the side bars; Outstan 'ng ears 48, carried by the lower apron, rest upon the upper ends of the springs. By this construction, it will be evident that the aprons are capable of lateral movement and are furthermore vertically adjustable.

The lower ends of the posts 10 have longitudinally disposed slots 49, in which are engaged clamping bolts 50. The heads of these bolts carry upright springs 51, on the upper ends of which rest outstanding ears 52, fastened to an oblong belt carrying frame 53. This frame is referably located at an inclination, and is isposed below the guidev pan 39. In its ends are journaled rollers 54,

around which passes a concentrator belt 55,

guide rollers 56 being employed to support intermediate portions of the upper stretch of the belt. The frame furthermore has depending central hangers 57, in which is journaled a guide roller 58. The concentrator belt 59 passes about the rollers 54 and beneath the guide rollers 58, which guide rollers maintain the central portion of the lower stretch of the belt within a pan 59.

A pump 60 is located at one corner of the frame, and the-plunger thereof has a rod 61 that projects above the pump. A discharge pipe 62, exten from the pump, leads up- 65 wardly to the et end of the screen, and

by links 41 secured to the upper side ars of' has a discharge nozzle-63 projectifig thereinto. A branch 64, from the pipe 62, extends transversely of the up er end of the belt 55, and is perforated, as sliown at 65.

A driving shaft 66 is journaled on one side 70 of the frame, and may be operated by any suitable means, as for instance, a handle crank 67. A countershaft 68 is 'journaled on the same side of theframe b'elowthe, shaft 66, and is connected thereto by sprocket gearing 69. The ends of the countershaft. carry crank disks 70, and the pi, disks are connected to the apr men 72. Another count'ersha I below the shaft 68, and comprise 's '80 73 and 74 connected by a universal joint 75. The section73 is geared to the drive shaft 66 by sprocket mechanism 76. Thes is capable of a swinging movemeii free end is j ournaled in a boxing 7 7. I boxing is also j'ournaled ashaft 78 extending from one end of one of the rollers 54 of the concentrator belt, and has a worm wheel 79 thereon. A worm 80,- carriedby the shaft section 74, cooperates with the worm wheel 79. The shaft section 7 3- is furthermore provided with cranks 81, which cranks are connected to the belt carrier frame by pitmen 82. The rear end of the driving shaft 66 has a crank wheel 83, provided with a radially disposed series of openings 84, in any of which the crank pin 85 may be placed, as shown in Fig. 9. A walking beam 86 is fulcrumed upon one. end of the frame, and has a link connection 87 with the upper endof the, piston or plunger rod 61, the other end of f the walking beam having a pitmfan (sens s: tion 88 with. the crank pin 85. In operation, the material is directed'iby" the chute 30 into the screen, and is there subjected to a spray of water delivered by the pump 60 through the pipe 62 and nozzle 63. The smaller particles pass through the screen wall 20, while the heavier material is discharged into the trough 28. The material, which passes through the screen 20 is again graded by the screen 21, part being delivered into the tailings trough 21, the remainder falling uponthe upper'portioniof the upper apron. This material passes'over the amalgamator aprons, which are given a rapid transverse reciprocation, and from thence fall upon the pan 39. This pan may be of copper, but for ordinary purposes, sheet iron has been found entirely satisfactory. The material is finally delivered upon the belt 55, which belt is not only. longitudinally by the driving .rnean described, but is also given a rapid e, shaking movement, inasmuch as the .12 carrying it is connected to the cranks 81, by

the links 82. l 1

It will be evident that this structure is comparatively simple, and experience has demonstratedthat it is entirely effective In this-BS5 I paratively small amount of water is needed to successfully operate the machine, and

3 there is no danger of the aprons becoming ,an arm clogged with material, inasmuch as the pockets' are very shallow: The amount of water can be readily varied by varying the stroke of the pump, this being accomplished by placi the crank in 85 nearer or farther away fiom the she t that carries the crank wheel 83.- The supply of water is thus regulated without altering the speed of the drivi means.

$rom the foregoing, it is thought that the construction, operatlon, and many advantages of the herein'described invention, will be a parent to those skilled in the art, without fbrther description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the s irit or sacrificing any of the advantages o the invention.

Having thus fully described my invention, What I c aim as new, and desire to secure-by Letters Patent, is:

1. In a machi e of the character described, the combination with a supporting frame, of a bracket ha spaced depending legs vertically adjustab e on'the supporting frame, means for holding the le at different positions on the supporting ame, rollers j ournaled on the bracket, a screen ha its lower-end rotatablymounted on the rollers, projecting rearwardly from the bracket, a tailings' receiving trough pivoted at its upper end on the arm in rear of the bracket and below the adjacent end of the screen, and a riflie table ocated longitudinally beneath the screen and trouglr and extend' beyond the-same, recei the material om the former, said troug extending transversely of and beyond the side of the table, preventing the tail from the screen falling upon said rifile tab 0.

2. In a machine of the character described, the combination with a supporting frame, of a bracket adjustably mounted thereon and having wheels, grooved wheels journaled on the frame, a rotary inclined screen 'hav' its lower end mounted on the .wheels of the bracket and its upper end provided .with an annular flange thatenga'ges in the grooves ofythe other wheels, an arm carried by the bracket, a tailings'receiving trough associated with the discharge of the. screen and having a pintle rotatably mounted in the arm, and se arating means located longitudlinally be ow the screen and the trough am through the screen, said trough being located above these arating means between the ends thereof and swinging to positions to deliver on opposite sides of the separating means.

3. Ina machine of the character described,

. a separator comprising an open frame formed of lo 'itudinal side bars and a center bar, cross ars connecting the center and side bars at intervals and hav' upstandin projections at their ends wh ibli are locate at the inner sides of the side bars and on opposite sides of the center bar, and a bottom for the apron body formed of sheet material extending from end to end of said body and havin sect-ions thereof disposed receiving the material that passes in substantially orizontal relation, said sections extending from thelower ed e of one cross bar to a position between t e upper and lower edges of the next lower, and means for transversely shaking said se arator.

In testimony that I claim t e foregoing as my own, I have hereto afiixed my s1gna ture in the presence of two witnesses.
